Your Neighbors Since 1999
David Daffan began in HVAC at 18 when the business launched in 1999. David was Daffan’s first service technician, quickly becoming Service Manager and then Co-Owner when his uncle sold the company in 2010. In 2021, after his partner retired, David became the sole owner, continuing to build something he could be proud of. Grounded in Christian values and a genuine desire to serve this community, David and his wife, Shanee, have grown Daffan into the largest residential HVAC company in the Granbury area, earning an A+ BBB rating and “Best AC Company in Hood County” for more than 16 years running.
Today, those same values still drive every decision. With David growing up in Glen Rose and Shanee born and raised in Granbury, their local roots shape how they invest in their team, care for customers, and treat every home they enter with the same respect they’d want in their own. Their focus is on serving with integrity, being good stewards of this blessing from the Lord. When you call Daffan, you’re not getting a call center or a private-equity chain. You’re getting your neighbors.

The Maintenance Club: Smarter Than Waiting for Something to Break
HVAC problems rarely announce themselves. They build quietly until something fails, usually in the middle of a Texas summer. Club membership keeps that from happening with twice-yearly (or annual) tune-ups, 50% off service call fees, 20% off repairs, zero overtime charges, and a 24-hour arrival guarantee.
We Show Up for Our Community (and for Each Other)
Being part of this community means more than running service calls across Hood County. It means showing up for the parade, investing in our team, and genuinely caring about what happens in this town. The people who represent Daffan out in the field are the same ones celebrating together, growing together, and looking out for each other off the clock. Community starts from the inside out!
